AMHERST, Mass. – Work by University of Massachusetts Amherst astronomer Martin D. Weinberg and colleagues at the University of California Berkeley suggests that the most prominent of the Milky Way’s satellite galaxies, the Magellanic Clouds, are interacting with the Milky Way’s ghostly dark matter to create a mysterious warp in the galactic disk that has puzzled astronomers for half a century.

The Office of Waste Management (OWM) is working to maintain UMass Amherst''s status as a Top 20 recycling university, according to general manager John Pepi, who is planning new efforts to recruit and train departmental coordinators.
